It was weird. I felt like I had been reading this for forever, and only managed to get past 25%. It started to feel like a chore. Still, I didn’t find anything particularly wrong with it, so I continued. Until our dashing hero sells a hundred people and justifies himself to the fMC by saying “it was a lot of money”. Wow. Such an upstanding individual. I cannot read anymore.
There are some very weird stylistic choices, and they are not consistent across instances of the same, for example, some words are omitted from conversations because fMC doesn’t understand, but others are written in English and she seems like an idiot for not getting the meaning. For example, she thinks “I don’t understand the word ‘commander’”, and I think "How?” Why was this word actually used, when previously, whenever she didn’t understand a word, it was just omitted from the text? Same with “volunteer”. At some point she asks someone to repeat the word, and they repeat it, enunciating the syllables, in English. So I was dumbfounded. Why didn’t she understand this basic word?
Another thing is that they constantly called her "Volunteer 4711”—all the time, sometimes twice in the same sentence. It was tiresome. And she just accepted it without protest, as she accepts pretty much everything else. And I kept wondering why they called slaves “volunteers.” I kept thinking, “I don’t think it means what you think it means.”
I got no real sense of the world. Only MMC is ever described in any detail, the planet fMC arrives at is just described as “purple” and with a desertic climate, but that’s it. I have no idea what the farm she was at looked like, either. She doesn’t even know what they farm, and she’s there for months. I have no idea why the farmers hate this Commander guy, or what he commands. What kind of government do they have? Who the hell do they fight with? What is the Empire? All of this is mentioned at some point, but never explained, as if the reader should already know these things. We get the most mundane things described in detail (like him making her feed, undress, and bathe him) but not this stuff? Also, we get time skips, and fMC doesn’t even bother to count the days or something, so she doesn’t have an idea of how much time has passed, and neither does the reader.
The doctor that initially buys her does some bad things, but they're never questioned, not even by the fMC. Most of the time, she acts as if she was born into this life instead of being forcibly brought into it just months before. She doesn’t question anything, she just ducks her head and keeps obeying.
And the final thing, no one, NO ONE is ever named. MMC is just “the Commander”, and fMC is “Volunteer 4711”. And the dehumanizing, debasing nature of that practice is never addressed nor questioned. I don't know what kind of commentary the author was trying to make, but she absolutely failed, in my opinion.
